Objectives: The brain and autonomic nervous system are tightly interconnected and may be involved in various psychiatric conditions.We explored whether electroencephalographic (EEG) coherence and vagally mediated heart rate variability (vmHRV) differ between male children with autism spectrum disorder (ASD) and typically developing (TD) children, and how these measures are associated with the clinical characteristics of ASD. Methods: We recorded resting-state EEG and vmHRV in 14 male children with ASD and 14 TD children. The Social Responsiveness Scale (SRS) was used to assess the clinical characteristics of the ASD group. Results: vmHRV measures (root mean square of successive RR intervals [RMSSD], percentage of successive RR intervals that differ by more than 50 ms [pNN50], and high-frequnecy power) did not differ between the ASD and TD groups. By contrast, the beta1 coherence between the T5 and T6 electrodes (beta1 coherence [T5–T6]) was lower in the ASD group than in the TD group, even after correction for multiple comparisons. This coherence measure demonstrated a positive correlation with RMSSD and a negative correlation with the SRS social motivation subscale score (SRS-Motivation). Moreover, pNN50 acted as a moderator of the association between beta1 coherence (T5–T6) and SRS-Motivation. Conclusion Resting-state EEG coherence may be associated with the clinical characteristics of ASD, and vmHRV may exert a moderating effect on this relationship. These preliminary findings suggest that the concurrent evaluation of brain and autonomic functions can be useful for elucidating the pathophysiology of ASD.

Objective: Many studies have explored sense of self in individuals with autism spectrum disorder (ASD); however, few have reported on their experience of “disembodiment.” This study aimed to investigate the differences in brain activity between patients with ASD and neurotypicals (NTs) under conditions causing disembodiment and to examine the correlation between their interoceptive abilities and disembodiment-related brain activity. Methods: 18 Participants with ASD and 21 NTs completed psychological evaluations, interoceptive abilities measurement, and functional magnetic resonance imaging (fMRI). The fMRI images were taken while the participants performed tasks involving ball-throwing animations. The task focused on either self-agency related to ball-throwing (Agency Task) or the spatial location of a ball (Location Task). The animations were presented from constantly changing perspective (Changing View) or fixed perspective (Fixed View). The disembodiment-related condition was the interaction between the Agency Task and Changing View. Results: Participants with ASD exhibited higher activation than NTs in regions near the left parieto-temporo-occipital junction, left precuneus, left hippocampus, and other brain areas. Furthermore, interoceptive accuracy was negatively correlated with the activity of the left superior parietal and posterior midcingulate areas, whereas interoceptive trait prediction error was positively correlated with the activity of the left hippocampus, mid-temporal area, and left posterior cingulate area in participants with ASD. Conclusion These results suggest that disembodiment-related brain activation might be easily manifested by the interaction between perspective-shifting and the experience of agency, and that interoceptive abilities might be related to disembodiment-related brain activation in individuals with ASD.

Background and Objectives: The risk profiles, procedural characteristics, and clinical outcomes for women undergoing bifurcation percutaneous coronary intervention (PCI) are not well defined compared to those in men. Methods: COronary BIfurcation Stenting III (COBIS III) is a multicenter, real-world registry of 2,648 patients with bifurcation lesions treated with second-generation drug-eluting stents.We compared the angiographic and procedural characteristics and clinical outcomes based on sex. The primary outcome was 5-year target lesion failure (TLF), a composite of cardiac death, myocardial infarction, and target lesion revascularization. Results: Women (n=635, 24%) were older, had hypertension and diabetes more often, and had smaller main vessel and side branch reference diameters than men. The pre- and post-PCI angiographic percentage diameter stenoses of the main vessel and side branch were comparable between women and men. There were no differences in procedural characteristics between the sexes. Women and men had a similar risk of TLF (6.3% vs. 7.1%, p=0.63) as well as its individual components and sex was not an independent predictor of TLF. This finding was consistent in the left main and 2 stenting subgroups. Conclusions In patients undergoing bifurcation PCI, sex was not an independent predictor of adverse outcome.
